FIELD OF THE INVENTION

This invention relates generally to an applicator and more specifically to an applicator that includes a reservoir body and cap that is formed integral with the reservoir body and that is separable from the reservoir body to allow for a release and dispersion of contents housed within the reservoir body of the applicator.

BACKGROUND OF THE INVENTION

Applicators designed for various purposes to deliver liquid, gel, or the like are well known. Such applicators typically include a housing (i.e., a tube or reservoir body) that has at least an opening formed in one end thereof and a cap that can be secured to the housing to seal the opening by screwing, snapping or sliding the cap over an end of the housing with the opening formed therein to seal the applicator. Alternatively, known applicators may include a cap that is permanently fixed to a body of the applicator to aid in dispensing contents housed therein by depressing the cap and/or articulating the cap.

However, the designs of many existing applicators have several drawbacks. For example, known applicators allow for potential leakage and/or contamination and/or evaporation of the contents stored within the housing of an applicator, do not allow for a direct application of the contents housed within the applicator at a desired contact site, and/or are cumbersome to use. Additionally, many known applicator designs do not allow for all measured contents to be released from the housing. Commonly, this occurs because surfaces within the housing of the applicator are angled, prohibiting all of the contents stored therein from being dispensed therefrom. For example, at least one cavity may be formed upon puncturing the housing to create an opening or unsealing an opening formed in the body of a housing of an applicator, which in turn can result in trapping fluid within the body of the housing. It is important in many instances that all of the contents within the housing be dispensed therefrom. In the case of an animal, applicators regularly house a specific amount of medicament to apply as a measured dosage onto the skin of an animal and it is important that the full measured dosage is applied to the animal to ensure the medicament works as intended.

Additionally, for existing applicators in which a cap or other covering element must be broken (e.g., snapped) or cut to disassociate the cap or other covering element from the reservoir body, a region of the applicator where the cap or other covering element has been removed regularly forms a sharp edge. When the applicator comes in contact, as is commonly the case, with a surface (e.g., the skin of an animal), the sharp edge can cause damage or harm to the surface (e.g., irritate or cut the skin of an animal).

Further, in many instances, due to the design of a cap or other covering element for known applicators, when the cap or other covering element is removed or separated from a housing, the contents housed within the applicator can unexpectedly be dispensed from the applicator and can contact an undesired surface (e.g., hands of a human).

SUMMARY OF THE INVENTION

The present invention is directed to an applicator assembly that includes a body and a cap that is integrally formed therewith. The cap is configured to be articulated, levered, pulled and/or twisted to permanently separate the cap from the body and to allow contents (e.g., fluid) to be dispensed from the applicator directly onto a surface (e.g., the skin of an animal). The one-piece design reduces manufacturing cost by producing the applicator as a single, molded element that does not require assembly while ensuring the contents housed within the applicator remain in an air-tight, sealed reservoir until the cap is separated from the body of the applicator.

In an embodiment, the present invention is directed to an applicator that comprises a reservoir body, a neck that extends from the reservoir body and includes an exposable opening at a distal end thereof and a shroud that extends from the distal end about the opening and a cap that is in fluid communication with and releasably fixed to the distal end of the neck, fully encompassing the opening in the neck and sealing the reservoir body.

In an embodiment, the reservoir body, the neck and the cap are a single element. The applicator assembly can be comprised entirely from a polymeric material. At least the reservoir body can include a non-slip coating and be comprised of a flexible material.

The cap can include a projection that extends from the neck. A handle can extend, at least in part, at an angle from the projection. The projection can be a connecting point that is substantially circular and includes an internal cavity that is aligned with the exposable opening in the neck.

The handle can extend substantially along a length of the neck. The handle can be substantially L-shaped such that the handle can include a first arm that extends substantially transverse to and from the projection and a second arm that extends at an angle from the first projection along the neck. The second arm of the handle can extend at an angle of about 90 degrees from the distal end of the neck. The handle can also include a rib that extends substantially along a surface thereof.

The projection can be a frangible port defined by a groove, a notch or an undercut that extends inwardly from an outer periphery thereof to aid in facilitating separation of the cap from the neck at a specific location to uncover the exposable opening and minimize fragmentation at the breaking point between the neck and projection when removing the cap. The frangible portion can extend at an angle from the outer periphery of the projection, can extend at least partially about the outer periphery of the projection or entirely about the outer periphery of the projection and can include a plurality of frangible portions.

In an embodiment, the frangible portion can extend about the outer periphery of the projection adjacent an outer surface of a distal end of the neck to ensure separation of the cap when removed at about the distal end of the neck. In another embodiment, the projection can include a sidewall that has a first surface and a second surface that is spaced from the first surface and substantially aligned with the exposable opening and the frangible portion can extend inwardly from the first surface toward the second surface to facilitate separation of the cap from the neck. In further embodiment, frangible portion can extend from an outer surface at a distal end of the neck toward an inner cavity of the neck and about the exposable opening. In yet a further embodiment, the frangible portion can extend from an outer surface at a distal end of the neck toward an inner cavity of the neck and about the exposable opening and the frangible portion can extend inwardly from an outer surface of the projection, adjacent the distal end of the neck to facilitate separation of the cap from the neck.

The shroud can be comprised of a plurality of protrusions that are spaced from each other and extend about an outer periphery of the neck. The shroud can include a first protrusion that extends from a first portion of an outer periphery of the neck and a second protrusion that is spaced at least by the opening in the neck from the first protrusion, extends at a second portion of an outer periphery of the neck such that the first protrusion and the second protrusion form a recessed channel at the opening to aid in dispensing the contents housed within the reservoir body and neck when the neck is in direct contact with a surface.

In another embodiment, the present invention is directed to a method of forming an applicator where the method comprises the steps of molding the applicator as a single element that includes a reservoir body, a neck that extends from a first end of the reservoir body and includes an exposable opening at a distal end thereof and a shroud that extends from the distal end about the opening and a cap that is integrally formed with and releasably fixed to the distal end of the neck, fully encompassing the opening in the neck and sealing the reservoir body, filling the applicator with a fluid and sealing a second end of the reservoir body.

In yet another embodiment, the present invention is directed to a method of using an applicator comprising the steps of providing an applicator that includes a reservoir body, a neck that extends from the reservoir body and includes an exposable opening at a distal end thereof and a shroud that extends from the distal end about the exposable opening and a cap that is integrally formed with and releasably fixed to the distal end of the neck, fully encompassing the opening in the neck and sealing the reservoir body, holding the reservoir body with a first hand, gripping the cap with a second hand and separating the cap from the neck of the applicator. The cap can be separated from the neck by at least one of rotating, levering and pulling the cap away from the neck so as to separate the cap from the applicator.

The cap can be comprised of a projection that, in an assembled state, is in fluid communication with the neck and encompasses the exposable opening in the neck, a handle that includes a first arm extending substantially transverse to and from the projection and a second arm extending at an angle from the first projection along the neck. In an embodiment, the method can further comprise the step of gripping the second arm and at least one of lifting, pulling and rotating the second arm away from the neck to permanently remove the cap from the applicator and at least one of rotating, twisting and pulling the cap to permanently remove the cap from the applicator.

The shroud can be comprised of a plurality of protrusions that are spaced from each other and extend about an outer periphery of the neck defining a channel between the protrusions in the area of the opening at the distal end of the neck, and, in an embodiment, the method can further comprise the step of contacting the tip of the applicator with a surface wherein the protrusions aid in allowing contents housed within the applicator to be released from the applicator and flow onto the surface.

 DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

With reference now to the drawings, and in particular to FIGS. 1-19, embodiments of applicator assemblies embodying the principles and concepts of the present invention will be described.

An embodiment of an applicator assembly, which is generally designated by reference numeral 10, is shown in FIGS. 1-5. The applicator 10 is a one-piece element that includes a reservoir body 12 that is defined by a housing 14 and a neck 16 that extends from the housing 14 and a cap 18 that is integrally formed with the reservoir body 12 and that extends from a distal end 15 (see FIG. 8) of the neck 16. After introducing contents (e.g., liquid, gel, etc.) into the reservoir body 12 during manufacturing, an end 13 of the reservoir body 12, opposite that of the distal end of the neck 16, can be heated to seal the contents within the reservoir body 12. It is noted that the size of the reservoir body 12 is not limited to a specific size, but rather can vary depending on the volume of contents desired to be housed therein.

By producing the applicator 10 assembly as a one-piece element, the manufacturing cost can be reduced as the applicator assembly 10 can be constructed in a single process, eliminating the need for additional labor to produce the applicator assembly 10 and reducing the time required to manufacture the applicator assembly 10. Additionally, by forming the applicator assembly 10 as a one-piece element, the contents housed in the applicator 10 will remain sealed within the reservoir body 12 until the cap 18 is removed, substantially eliminating the likelihood that the applicator assembly 10 will leak.

The applicator assembly 10 can be comprised of a polymeric or a plastic material, such as a polypropylene and polyethylene, that has been injection molded. The reservoir body 12 can include a non-slip coating and be comprised of a flexible material.

FIG. 7, which is a cross-sectional view of FIG. 4 taken along line A-A of FIG. 6. FIG. 8 is a detail sectional view of FIG. 7 further depicting features of the neck 16 and the cap 18. As shown, the neck 16 includes a safety shroud that is comprised of a first projection 20 and a second projection 22 that extend from the neck 16 at a distal end 15 thereof. The first projection 20 and the second projection 22 are spaced from each other by a channel 26 (See FIGS. 17 and 18). Although two shroud projections 20, 22 are shown, it is understood that the shroud can include any number of projections that extend from the distal end of the neck 16.

When the cap 18 is removed from the neck 16, the opening 24 is exposed and a rough or jagged surface 17 (See FIGS. 16-18) is commonly formed about the periphery of the opening 24. If the distal end 15 of the neck 16 was placed in direct contact with a surface S after removal of the cap 18, such as the skin of an animal, the sharp surface 17 formed around the opening 24 can cause irritation to the skin of the animal or create a cut in the skin of the animal. However, the projections 20, 22 of the shroud, which substantially surrounds the opening 24, extends from the distal end of the neck 16 to ensure the opening 24 will not be in direct contact with an application site and prevent injury or irritation at the application site. The projections 20, 22 of the shroud also acts to create a gap between the opening 24 and the application site, to prevent the applicator 10 from becoming obstructed and allowing the contents housed in the applicator 10 to flow out of the opening 24 and to a desired contact site.

As can be seen in FIGS. 7 and 8, the cap 18 extends from the distal end 15 of the neck 16, fully encompassing the opening 24. The cap 18 includes a protrusion or connecting point 28 that has an inner surface 27 and is in fluid communication with the neck 16, fully encompassing the opening 24 of the neck 16 and preventing leakage at the opening 24, a handle 30 that is comprised of a first leg 32 which extends substantially perpendicular to the protrusion 28 and distal end 15 of the neck 16 and a second leg 34 that extends at an angle from the first leg 32 along the length of the neck 16. In an embodiment, the first leg 32 can extend at an angle of about 90 degrees from the distal end 15 of the neck 16. A rib 35 can extend along at least one of the ventral surface 30a and dorsal surface 30b of the handle 30 to provide rigidity thereto.

As shown, the protrusion 28 is cylindrical. However, the protrusion 28 can take the form of any desired shape. Additionally, as depicted in FIG. 8, the projection 28 includes a recess 31 formed therein that is aligned with the opening 24 in the neck 16. The recess 31 is intended to aid in reducing the surface area at the protrusion 28 and facilitate separation of the protrusion 28 and neck 16, when desired. As depicted in FIG. 8, an outer surface 29 of the protrusion 28 can include a frangible portion 33 defined an undercut, a notch or a channel that extends from an outer periphery of the protrusion 28 toward the opening 24 in the neck 16. The frangible portion 33 is intended to facilitate the separation of the connection between the cap 18 and neck 16 near the opening 24 of the neck 16. Although the frangible portion 33 is depicted in FIGS. 1 and 8 as extending inwardly about the entirety of the outer periphery of the protrusion 28 of the cap 18, the configuration should not be limiting in scope as the frangible portion can take any form and be located at any point about the cap 18 and/or the neck 16. For example, as shown in FIG. 9, at least one frangible portion 33a can extend inwardly from a location about the outer surface of the protrusion 28a of the cap 18a, near the outer surface of the distal end 15a of the neck 14a. As depicted in an embodiment in FIG. 10, at least one frangible portion defined by an undercut 33b can extend from an inner surface 27b of the protrusion 28b toward an outer surface of the protrusion 28b. As depicted in an embodiment in FIGS. 11 and 12, at least one frangible portion defined by a channel 33c can be spaced from the protrusion 28c and extend from the outer surface of the distal end 15c of the neck 14c toward a cavity with the neck 14c. As can be seen in an embodiment in FIG. 13, at least one frangible portion defined by an undercut 33d can extend at least partially about the outer surface of the protrusion 28d toward the opening 24d in the neck 14d and at least one frangible portion defined by a channel 33dd can extend from the outer surface of the distal end 15d of the neck 14d toward the cavity 11d within the neck 14d at least partially about the protrusion 28d.

When an individual desires to remove the cap 18 from the reservoir body 12 as shown in FIGS. 14A through 15B, the individual can grasp the reservoir body 12 in an upright position with one hand and grip the second leg 34 of the cap 18 and permanently separate the cap 18 away from the neck 16 by applying a torque to the second leg 34. Upon an application of torque to separate the cap 18 from the reservoir body 12, the protrusion 28 of the cap 18 will separate from the neck 14 at about the frangible portion 33, exposing the opening 24 in the neck 16 (See FIGS. 16 and 17) to allow the contents housed therein to be dispensed therefrom. To apply the contents (e.g., fluid) onto a surface (e.g., the skin of an animal) (See FIG. 18), the individual can then rotate the applicator assembly 10 and directly apply the shroud against the surface, allowing the contents to flow into the channel 26 and onto the surface S while the rough surface 17 formed about the opening 24 is prevented from contacting the surface S.

As depicted in an embodiment in FIG. 19, the internal sidewalls 37 of the housing 14 and neck can be angled toward the distal end 15 of the neck 16 to aid in disbursement of the contents housed in the reservoir body 12 and ensure at most minimal retention of said contents in the reservoir body 12.

The foregoing description and accompanying drawings illustrate principles, exemplary embodiments, and modes of operation of the present invention. However, the present invention should not be construed as being limited to the particular embodiments disclosed herein. Variations to the embodiments discussed above will be appreciated by those skilled in the art without departing from the scope of the invention. Accordingly, the above-described embodiments and accompanying drawings should be regarded as illustrative rather than restrictive.
